2014-03-04 04:26:18 -0500 | asked a question | how to redraw a 3d map offline according to the collected data I have used kinect-3d-slam of MRPT to collect a file of data. It is printed in real time a 3d map of a small room. Now I have stored the data like: 2.153973 1.229960 0.884632 2.180799 1.234268 0.895650 2.194463 1.219843 0.901262 2.236500 1.228155 0.918526 2.222315 1.209146 0.912700 2.236500 1.194281 0.918526 2.222315 1.175487 0.912700 2.250876 1.186806 0.924430 2.265433 1.171606 0.930409 2.265433 1.148731 0.930409 2.250876 1.126198 0.924430 2.250876 1.099682 0.924430 2.265433 1.083919 0.930409 2.280179 1.071788 0.936464 2.280179 1.048764 0.936464 2.280179 1.025740 0.936464 2.265433 0.996232 0.930409 2.295117 0.993836 0.942600 2.280179 0.979693 0.936464 2.265433 0.950482 0.930409 2.265433 0.927607 0.930409 2.280179 0.914458 0.936464 2.265433 0.889482 0.930409 2.280179 0.876085 0.936464 2.265433 0.862795 0.930409 2.265433 0.839920 0.930409 2.265433 0.817045 0.930409 2.280179 0.803177 0.936464 2.265433 0.782733 0.930409 and want to redraw it in other time.

Seems no driver I have installed freenect from and also blacklist gspca_kinect(I am using Ubuntu 12.04 LTS) But when I try the command It says that and then I try lsusb it shows me like These are kinect's and I could not find something like camera or others.

2014-01-14 18:51:26 -0500 | asked a question | kinect 3D map, need more detail on the result Hi, I have tried ROS RGBDSLAM but failed for the installation since the command no longer exists --rosdep-install I tried the Kinect-3D-slam in MRPT http://www.mrpt.org/list-of-mrpt-apps/application-kinect-3d-slam/ The result of a small room is good actually. But I would like to add more color details on to the model sice the result looks only points. This method seems only projects the depth information which is extracted! I would like to upload the image result but I do not have enough karma. Is there any library or package for helping print whole RGB information on to the depth data to make the result more visible? I know that post a MRPT application question here on ROS is not appropriate, but I need your help. Thanks a lot. |
2014-01-14 18:37:42 -0500 | commented answer | 3D slam problems I installed also fuerte but it still could not use the command --rosdep-install. It seems that ROS has removed that command. |

Since there is command problem starting from Or is there any new package application performing the same as the video in the website? I would like to sketch the 3D map of a big room like the function showed in the website. Thank you. |

2013-11-12 15:49:36 -0500 | asked a question | Rosbag playback problem with topic status transform alert I am following the openni_launch/Tutorials/BagRecordingPlayback to record and play back the kinect.bag I am using Ubuntu 12.04 and ROS Hydro. And this is my command in procedure: Till here, it all works well. Then I continue to play back. I close (Ctrl-C) the ROS freenect driver I continue. Up to here, I see in rviz Time, ROS Time is running the same as Wall Time. So I change the command procedure: And I see that the ROS Time stops at 00.0 with Wall Time keeps running. Then I try There is something wrong in Rviz PointCloud2 Status: Error Points (good) Transform [sender=/camera/camera_nodelet_manager] Message removed because it is too old (frame=[/camera_rgb_optical_frame], stamp=[1384312642.156354048]) And also there is nothing played in the Rviz. What is the problem? You could also see my previous question to have more information if you like. http://answers.ros.org/question/98611/rosbag-record-with-kinect-facing-a-disk-memory-space-problem/ Thanks a lot. |
2013-11-08 03:53:52 -0500 | commented answer | 'Rosbag record' with Kinect, facing a disk memory space problem Plz see [edit 3]. And I should try to get familiar with the concept of the topic of camera and rviz. I will try to show the image. It is so nice to meet you here. Thanks a lot for your great helping. |
2013-11-08 03:08:53 -0500 | commented answer | 'Rosbag record' with Kinect, facing a disk memory space problem I remove -O directly and it works. I am sorry that I am a fresh man in the ROS world. I need time to learn your command. Another thing is that I just want to know how to play back the data in a visualization window or something. It just play back in the terminal, I cant see anything. Thanks |

2013-11-08 02:45:01 -0500 | edited question | 'Rosbag record' with Kinect, facing a disk memory space problem while I want to record kinect data, using The terminal shows that Why is it? I check my File Systems under System monitor How could I fix it? Thanks! edited: 'rosbag record' directly creats the kinect.bag under 'Home' of Ubuntu, I don't know how to change the location. The location is also shown in the 'kinect.bag properties' window with 'Location: /root'. And when I try It shows that Is there any command to change the kinect.bag location? To be summarized, it implies that the disk space is not enough. how can I change the location of the recorded kinect.bag file into a larger disk location? [edit] I try and then run rviz and then But cant visualize the data. And what is '--limit=60' means? And now I just only record only 2 seconds, how to make it longer? Thank you! [edit 2] I tried slightly different from the above one by changing image_raw to image. And I run rosbag record and it started to record but then gave this Now I cant see new kinect.bag file in the directory. It is the old one. I have set false. Why is it? [edit 3] I followed the play back data tutorial http://wiki.ros.org/openni_launch/Tutorials/BagRecordingPlayback Found that ROS time in rviz is the same as the running play back bag time in the terminal. But there was nothing shown in the rviz. So either I did not record anything or I used a wrong topic. I checked the recorded file, it is 276.5 MB. So I could use a wrong topic to show it? |
2013-11-08 02:19:08 -0500 | commented answer | 'Rosbag record' with Kinect, facing a disk memory space problem I just cant visualize the data. rviz shows nothing. Is it because I did not successfully record data into kinect.bag? And how to record longer say more than 2 seconds? |
